Description

SNOW CHAIN SNOW CHAIN

The present invention relates to a snow chain.

Generally, a tire used for a wheel of an automobile is a tire which rotates a tire by friction with the ground to drive the automobile, and when the vehicle is stopped or speed is reduced, Is used.

However, when the frictional resistance between the tire and the ground is set to be large considering the braking only, the fuel consumption is increased and the fuel consumption is reduced. Therefore, the design is based on the vehicle speed and the shape of the ground.

In general, particles such as liquids or sand, such as water, decrease the coefficient of friction between the ground and the tire so that the tire can not rotate against the ground and just slip.

If this phenomenon continues during driving, the vehicle will not be able to accelerate and will turn the wheels in place. If such a phenomenon occurs during the braking of the vehicle traveling at high speed, the vehicle will not be able to brak.

It's also a problem when it rains, but there is a bigger problem after snowfall, because snow on the ground or frozen snow will form ice on the road, so there is little friction between the ice and the tire.

Therefore, when the snow falls on the day or the snow that falls at night is frozen on the ground, braking can not be done.

Equipment used to prevent cars from slipping during accidents during snowy or icy roads in winter has a chain that winds on tires.

The chain is made of metal or rubber material to cover the tires of automobiles, thereby increasing the coefficient of friction between snow and ice accumulated on the ground, thereby preventing the vehicle from slipping.

Such a chain can increase the braking force of the automobile relatively. However, since it is difficult to mount or disassemble the tire, there is a great difficulty for the novice driver or the increasingly female driver to use the chain.

Even if the tire is mounted so as to surround the tire, when the tire is loosely mounted, the chain which has been mounted during traveling often breaks down and becomes impossible to be reused.

Accordingly, a method of spraying an adhesive and fine particles on the surface of a tire in the form of a spray is used so that the coefficient of friction with the ground can be increased without installing a chain.

However, this method temporarily increases the coefficient of friction of the automobile tire, but there are not many users because it can hardly perform when the vehicle is used for a long period of time or when snowfall or heavy snowfall occurs.

In addition, snow tires are the winter tires. These snow tires form the groove of the tires in a finer and more diverse way. At the same time, the breaker is molded in one piece to increase the coefficient of friction between the ground and the tire. So that a higher frictional force is exerted.

However, when the snow tires are downhill or the ground is very slippery, the braking effect is not good and there is a disadvantage that the tire must be changed according to season changes. When the ground is not slippery, It is difficult to increase the running speed of a car.

Although the above-mentioned non-slip products are relatively excellent in improving the braking effect of the automobile, there are limitations in the difficulty of mounting and weakness of the effect, and in protecting the vehicle from slipping of the ground.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a tire for a vehicle which is easy to attach and detach and has little projecting portion, And to provide a snow chain to be used by attaching.

A snow chain according to one aspect of the present invention includes an outer circumferential cover positioned to cover an outer circumferential surface contacting the road surface of the tire when the tire is mounted on the tire and a snow chain fixed to two edges of the outer circumferential surface cover, A cover including a side cover, a friction part formed on all or a part of a surface of the both surfaces of the outer circumference surface cover which increases frictional force, and both ends of the cover are connected to each other when the cover is mounted so as to surround the circumference of the automobile tire And the cover is placed on the automobile tire while the inner surface of a part of the cover is turned upside down so as to face the outside and then the automobile is moved to the front or rear side so that the cover is positioned between the ground and the automobile tire A part of the cover which has been turned over is turned back to its original shape, After the server is completely surround the car tire is fixed to both ends of the cover through the connection portion.

Referring to FIG. 2, the cover 100 includes an outer peripheral surface cover 110 and a side surface cover 120.

The outer circumferential surface cover 110 covers an outer circumferential surface of the outer surface of the tire contacting the road surface when the snow chain of the present invention is mounted on the automobile tire.

The outer circumferential surface cover 110 has a length l that encloses the entire circumference of the tire and a width that covers the thickness of the tire. The length l of the outer circumferential surface cover 110 may have a margin greater than the circumferential length of the tire circumferential surface to connect both ends of the outer circumferential surface cover 110. The length of the outer circumferential surface cover 110 may be larger than the thickness of the tire for connection to the side cover 120, Lt; / RTI >

In addition, the entire or a part of the surface of the outer peripheral surface cover 110 which faces the road surface is mounted on the whole or a part of the frictional portion 200 having frictional properties. That is, the friction portion 200 is formed on the outer surface of the cover 100.

When these frictional portions 200 are mounted on a part of the cover 100, the frictional portions 200 may have the same thickness and the same interval.

When the cover 100 is mounted on the tire, the outer circumference cover 110 is rotated by the tension of the tire 100 to be caught by the cover 100 due to friction between the rotation of the tire and the road surface. Further includes at least one seam 111 in the direction of rotation of the outer peripheral surface cover 110, i.e., in the circumferential direction of the tire, in order to prevent the cover 100 from being damaged.

The seam 111 can be made of a material such as yarn to make it soft and light, or to improve the durability of the cover 100 itself by using a material such as wire.

The side cover 120 covers the side surface of the outer surface of the tire when the snow chain of the present invention is mounted on the vehicle tire.

The side cover 120 is formed in a circular shape having the same shape as the side surface of the tire and having a hollow center in the middle. At this time, the thickness is equal to or less than the width of the side surface of the tire to be mounted.

In addition, the side cover 120 is not in the form of a continuous donut but has one incline (b) at a position corresponding to both ends of the outer circumference cover 110 for detachment to the tire.

The periphery of the side cover 120 formed in this way is fixedly coupled to the excess portion a of the outer cover 110 through a means such as sewing or adhesion.

In addition to the method of fixing the cover 100 using such a bonding portion, an inner friction portion (not shown) having frictional properties like the friction portion 200 is formed on the entire surface or a part of the surface of the both surfaces of the outer peripheral surface cover 110, Thereby increasing the frictional force between the tire and the inner surface of the outer surface cover 110 so that the tire does not idle inside the cover 100 when the vehicle is driven.

The cover 100 formed of the outer circumferential surface cover 110 and the side surface cover 120 formed as described above and coupled to each other is formed of a fabric such as a nonwoven fabric or a denim. When the cover 100 is mounted on the tire, To prevent the tire from falling out, it has a connecting portion 300 as follows.

3, the connection part 300 is formed at the position of the cut-away b in order to hold the cut-away portion b of the side cover 120 of the cover 100 from both sides and to connect and fix them.

The connecting portion 300 is formed by at least one of a belt, a buckle, a Velcro, and a ring to hold both ends of the side cover 120 about the folding b of the side cover 120, Is mounted on the tire, the cover 100 is fixed so as not to be detached.

When the connecting part 300 is the Velcro 320, one side of the side cover 120 is extended to one side of the side cover 120, and one side of the Velcro 320 is attached to the lower side of the extended side. The other side of the non-elongated side is affixed to the other side of the velcro 320 and the extended side is placed over the other side that is not extended.

Referring to FIGS. 1B, 4A and 4B, mounting of the snow chain according to an embodiment of the present invention to a tire 1 of an automobile will be described as follows.

First, the incised portion of the cover 100 is folded up as shown in FIG. 1B to prepare the inner surface I of the cover 100 to be exposed to the outside. At this time, the degree of folding can be arbitrarily determined by the user to be folded up so as to cover the portion of the tire not attached to the road surface.

The cover 100 thus prepared is folded down from the upper surface of the tire 1 in a folded state as shown in Fig. 4A. At this time, since the cover 100 is folded, the cover 100 can be fitted on the tire without being disturbed by the portion where the road surface and the tire 1 are in contact with each other.

The cover 100 is put on the tire 1 and then the automobile is moved so that the portion of the tire 1 directly contacting the road surface is rotated and raised so that the portion covered by the cover 100 is brought into contact with the road surface. At this time, the portion where the inner surface I is folded and exposed to the outside moves so as not to touch the road surface.

Then, fold it up and hold it upside down and pull it down in the direction of arrow (A). Through this operation, the exposed portion of the tire 1 is covered with the outer surface O of the cover 100.

Finally, when the cover 100 is fixed so as not to come off through the connecting portion 300, the mounting of the snow chain, which allows the vehicle to run smoothly on ice or snow, is completed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
